deep stall

A deep stall is an airplane stall where not only does the aircraft not get enough lift from the wind speed, but, there's enough wind to push the nose of the plane up which makes it impossible for the plane to pitch back down to exit the stall normally.
Basically there's not enough wind to lift the whole plane but there's enough lift to keep the nose up which removes the possibility to pitch down and escape the maneuver.

When the pilot entered a deep stall he sobbed violently.

"Captain I think we're fucked. We're in a deep stall now..."

"Why the hell aren't we pitching down!?" Oblivious pilot.

deep sockets = deep POCKETS

What you realize must be da case if someone owns both a standard set of ratchet-wrenches and a collection of elongated ones, as well.

Many assorted tools are often available for mere pennies on da dollar at yard sales and online marketplace sites, and so da "deep sockets = deep POCKETS" assumption is not necessarily true each and every time... before you start feeling envious of someone's exTENsive --- and therefore seemingly exPENsive --- array of lengthy tubular six-and-twelve-pointers, look them over carefully to see wheter they are either particularly new-looking or even all of da same brand. If not, then realize dat these collections may merely be da "cream of da crop" from random groupings of tools in jumbled chests and toolboxes dat their present owner had obtained on da cheap from here and there, and then had merely sifted out da best specimens and carefully arranged them into those neatly-sorted sets.

Pistol Deep

Being caught up in something that is way over one's head. Being "pistol deep" in something means there is a severity and gravity to a situation should not be taken lightly. Often used to refer to someone being in the depths of a addiction, on the run from authorities, or anyone who feels trapped in a situation with no way out. The stakes of being in a "pistol deep" situation are normally very high. This pistol part of the "pistol deep" is meant to emphasize this severity, giving a connotation that things could turn fatal or end badly.

I heard the mob is looking for Jessie, man he's really pistol deep in that shit.
